摘　　要：将轮胎断面划分为胎冠区域和非胎冠区域,采用有限元分析方法和灵敏度分析,建立滚动阻力和区域能量损耗的关系,进行低滚动阻力轮胎结构设计,达到降低滚动阻力的目的。结果表明,变化区域能量损耗与滚动阻力呈线性变化。胎面结构对胎冠区域能量损耗的贡献度高达69%,对胎冠区域能量变化起决定性作用。合理的降低1#和2#带束层宽度,能降低胎面能量损耗,2#带束层对于胎面能量损耗的灵敏度更高。耐磨胶、胎体层、三角胶&胎侧对非胎冠区域能量损耗的贡献度相当,在30%左右。合理的增加耐磨胶高度有利于耐磨胶和胎体能量损耗的降低。合理的降低三角胶高度会降低非胎冠区域能量损耗。基于区域能量损耗与轮胎结构关系,对轮胎胎体结构进行方案设计,最优方案比原始滚动阻力降低9.5%。The 2-D cross section of radial tire was divided into two areas:the crown and the non-crown.The aim of research was to reducing the rolling resistance by redesign structure.The relationship between regional energy loss and rolling resistance was established by the sensitivity analysis and finite element analysis(FEA).As a result,the energy loss of change region was consistent with the rolling resistance.In the crown region,the mainly contribution of the energy loss was tread structure,nearly up to 69%,which played a crucial role.Reasonably reducing the width of 1#and 2#belt could reduce the energy loss,and 2#has higher sensitivity for the loss energy.In the non-crown,abrasion,carcass,apex and sidewall had the same effect on the non-crown area loss energy,and the Contribution was about 30%.The region loss energy decline with the increase of abrasion height.The reduction of apex height also reduced the non-crown energy loss.Based on above,a final optimization was proposed,which was lower than original scheme by 9.5%.
